As hi-fi equipment becomes more sophisticated and complex, the circuits become more susceptible to interference from outside sources, particularly electromagnetic (EM) fields This problem is known as electromagnetic interference (EMI) Sometimes it is called radio-frequency interference (RFI) If a radio transmitter is operated near a hi-fi stereo system, the radio signals can be intercepted by the hi-fi wiring and peripherals, and delivered to the amplifier Unshielded interconnecting cables act as radio receiving antennas This problem is exacerbated if any of the connecting cables happen to resonate at the operating frequency of the radio transmitter In the hi-fi amplifier, the RF currents are rectified, causing changes in the audio gain Sometimes the signal data can be heard in the speakers or headset In most cases when EMI takes place in a hi-fi setup, the fault exists in the stereo system design, not in the radio transmitter The transmitter system is merely doing its job: generating and radiating electromagnetic signals! Several steps can be taken when installing a stereo hi-fi system to minimize the likelihood that EMI will occur:

So far in this book, we ve used the names of applications to refer to them For example, to make the application TextEdit take an action, we ve used a tell block to the application TextEdit :

SELECT DISTINCT [LastName],[FirstName] FROM [Person].[Contact] WHERE [LastName] LIKE '%quist'

A covering index on (LastName, FirstName) can still be used to satisfy this query, although it ll require an index scan, not an index seek, and as such will take longer and more page reads than a query that can seek. You don t even have to use the leftmost column of your covering index in your WHERE clause a covering index on (FirstName, LastName) can also be used to satisfy this select just as well. The rule that you need to have the most selective column first in your index isn t true for covering indexes, either. For instance, even though ContactID is more selective than FirstName, the following query runs faster against an index on (FirstName, ContactID) than against an index on (ContactID, FirstName):

Connect the stereo amplifier chassis to a good electrical ground Use shielded interconnecting cables as much as possible Use shielded (coaxial) speaker cables Keep all cables as short as possible

This means of referring to an application is straightforward and works fine as long as there s an application with the name you use If there s no application with that name, AppleScript displays the Choose Application dialog box to let you pick the application, which is much neater than displaying an error dialog box that merely chastises you for using the wrong name (If you cancel the Choose Application dialog box, AppleScript does give you that error) To make sure you get the application you intend, you can use the application s id property This property returns what s known as its bundle identifier for recent applications; if the application doesn t have a bundle identifier, the id property returns the creator code instead, an older means of identifying an application A bundle identifier takes the form comappleiTunes (for iTunes), while a creator code is a four-letter string for example, XCEL for Microsoft Office Excel 2004 for Mac

SELECT DISTINCT [ContactID] FROM [Person].[Contact] WHERE [FirstName] = N'Jane'

Covering indexes usually slow down modifications. This is a no-brainer. All indexes usually slow down modifications, including covering indexes. The one word I feel that I need to explain is usually I added it to the title of this section automatically, because blanket statements are rarely true in database programming. In the example in listing 5, a covering index speeds up a modification.

To communicate with the application, use a tell statement with application id and the application s bundle identifier or creator code as a string For example, to tell iTunes to do something:

If you have an amateur or citizens band (CB) radio station in your house and it causes EMI to your hi-fi system, perform these additional steps: Locate the radio transmitting antenna as far from the hi-fi equipment as possible Use the lowest possible transmitter output power that will ensure reliable communications Unfortunately, EMI problems can sometimes prove nigh impossible to eliminate This can be especially troublesome for amateur and CB radio operators when it damages relations with neighbors In these cases, old-fashioned diplomacy may work better than engineering-based attempts at resolution
